Virus? My computer has been sending error messages that I have a potential virus threat and provides virus protection options. WHen I select them it takes me to an advertiser page. Also, my wallpaper is changes and will not change back. When I select ctr -alt- dlt a message appears basically stating that the administrator has blocked this option. Finally, it will not let me download any virus removers and I believe the one I have is outdated because it doesn't find this virus. What else can I do


Firstly, the most important thing you can do is keep up-to-date virus protection-either a paid program like "Mcafee" or a free version, (which I'm not sold on but better than nothing)like AVG.....available here:http://free.avg.com/download-avg- ... Gateway 450SX4 Notebook
